I am currently Professor and Chair of the Department of Astronomy of the Ohio State University.

I also serve as chair of the Space Telescope Institute Council. The Space Telescope Institute Council is the management council for Space Telescope Science Institute, which operates the Hubble Space Telescope and will operate its successor, the James Webb Space Telescope, scheduled for launch in 2013. I carry out research on active galactic nuclei using Hubble Space Telescope and other telescopes.
